The present invention relates to novel pyridinium derivatives of formula I
wherein R¹ represents C₁₋₆ alkyl or aryl-C₁-₆ alkyl; R² represents aryl; Z is -O- or -NR³-; T is -O-, -NR⁴- or a single bond; R represents C₁₋₁₈ alkyl, C₁₋₁₈ haloalkyl, aryl, heteroaryl, aryl-C₁₋₆ alkyl or heteroaryl-C₁-₆ alkyl, and in addition, when T represents a single bond, R can also represent a phenyl or phenylmethyl radical substituted in the para or meta position by a 2-quinolylmethoxy group; R³ and R⁴ independently represent hydrogen, C₁₋₄ alkyl, aryl or C₁₋₄ alkylcarbonyl, and in addition, R³ and R⁴ may form a ring together when Z= NR³ and T= NR⁴, or R³ may be bonded to R to form a ring when Z= NR³; and W⁻ is a counter anion. These compounds are PAF antagonists.
本发明涉及公式I的新型吡啶衍生物,其中R¹代表C₁₋₆烷基或芳基-C₁-₆烷基;R²代表芳基;Z为-O-或-NR³-;T为-O-,-NR⁴-或单键;R代表C₁₋₁₈烷基,C₁₋₁₈卤代烷基,芳基,杂环芳基,芳基-C₁₋₆烷基或杂环芳基-C₁-₆烷基,另外,当T代表单键时,R还可以表示在对位或间位被2-喹啉甲氧基基团取代的苯基或苄基基团;R³和R⁴独立地表示氢,C₁₋₄烷基,芳基或C₁₋₄烷基羰基,另外,当Z= NR³且T= NR⁴时,R³和R⁴也可以一起形成环,或者当Z= NR³时,R³可以与R结合形成环;W⁻是一个对离子。这些化合物是PAF拮抗剂。
